SPECIFICATION forming part of Letters IEatent No. 522,655, dated July 10, 1894. Application tiled April 5, 1894. Serial No. 506.493. (No model.)

To aZZVwh/om it may concern.- v

Be it known that I, JOHN LEROY CREVEL- ING, of the city of Auburn, New York, have invented certain new and useful Improvements in Electric Railways, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification.'

My invention relates to the trolley which takes the main line current, and it consists in a new constrction of said trolley and in the proper disposition of the line wires so as' to present them properly to the trolley.

In the drawings Figure 1 is a transverse View of the roadway, A, representing the foundation, B, one of the usual track supporting yokes, C, the pavement, D, D, the rails secured to said yokes, E, E, the wheels F, and Gr, the axle and motor, respectively, of a car upon the same. The central openings,

' l-I, through the successiveryokes, B, form a conduit within which the two line wires, a, ct are carrledfthese wires connecting with the mam driving dynamo, as isusual. These line wires are secured to the brackets, b, b', byl

bolts, e, e', and are secured within the insulating blocks c, c', while covers, CZ, d", protecty secured, and insulated bya layer of non-conducting material, m. A pair of arms, fn., n,

on either side is pivoted at, p, toa portion of the slide, Z, and at, r, to a block, l@which is fitted to slide on theway, Z. A spring t, tends to draw r and p, together. Trolley wheels, o,

"u, are pivoted to the'outer ends of the arms central plate, K, (as shown by dotted lines in Fig. 1,) to the car motor, Gr, and returned through said central plate, K, to the slide, Z,

on the other side. These slides thus, through the wheels fv, fu, and arms, n, n, n, n, serving to convey the current from the wire 0 to the wire a. The pins,`s2, s2, limit the `travel of the blocks, s, s, `toward the pivots p, p.

Having thus described my invention, what VI claim as new, and desire to secure by Letters Patent, is-

1. An electric trolley, consisting ot' the depending plate, K, in combination with the trolleys, o, o, supported on either side thereof respectively by a pair of pivoted arms n, n.

' 2. In an electric railway, the combination of the trolley, comprising a dependent plate, K, the pivoted arms, n, fn, n, n, slides, Z, and

' wheels, fu, o, with the two wires placed on either side of the conduit or subway, H.
